explain why NADH and FADH2 are a type of energy currency in the cell
What are the functions of NADH,FADH2 . And what are the different inhibitors of cell respiration and how they inhibit.
Which of the following could explain why transfer of electrons from FADH2 to Coenzyme Q (CoQ) is not coupled to proton transfer, but transfer from NADH to Coenzyme Q is? Select one: a. FADH2 donates more electrons than NADH to the electron transport chain. b. Because FADH2 has higher affinity for electrons than Coenzyme Q c. Because FADH2 is a higher energy carrier than NADH d. Because the transfer of electrons from FADH2 to CoQ does not release enough energy....
3) Which of the following are the reasons why FADH2 produce less ATP compared to NADH? (3 points) I) Because it has lower oxidation potential compared to NADH II) Because it has lower reduction potential compared to NADH III) Because formation of FAD+ requires energy input IV) It pumps less number of H+ required for generation a) I and III b) III and IV c) I and IV d) II and IV
Why does oxidation of FADH2 provide less energy for the synthesis of ATP than oxidation of NADH in oxidative phosphorylation?
If a cell makes 5 NADH and 3 FADH2 molecules during cellular respiration, what is the total number of ATP molecules that will be made during the ETC? - Write your answer in the form of numbers and NOT IN WORDS)
Besides NADH and FADH2, what energy molecule is produced directly in the citric acid cycle? A. CO2 В. АТР c.cТР D, UTP E. None of the above
High-energy electrons from molecules of NADH and FADH2 are transferred to a chain of proteins within the electron transport chain. What is the final protein in the electron transport chain? O cytochromec oxygen O carbon dioxide NAD+ ubiquinone
Why does succinate DH give electrons to FADH2 rather than NADH? This requires looking at the electrochemical reduction potentials.
What will be the total number of molecules of NADH, FADH2, and
GTP that are synthesized if the citric acid cycle repeats 16 times
?
Part B What will be the total number of molecules of NADH, FADH2, and GTP that are synthesized if the citric acid cycle repeats 16 times? Express your answers as integers separated by commas. View Available Hint(s) Number of NADH, FADH2, GTP molecules Submit
In a cell, why must NADH be reoxidized? How does this happen in an organism that uses respiration? Fermentation? 2. Explain the chemiosmotic mechanism of ATP generation. How does oxidative phosphorylation compare with substrate level phosphorylation found in glycolysis and the Kreb’s cycle? 3. Which of the following yields the greatest energy for a cell: fermentation, anaerobic respiration, or aerobic respiration? Which yields the least? Why? 4. Explain what happens to glucose during glycolysis and respiration in terms of oxidation...
